rnarn-srorrrne APPARATUS.

T0 all whom, it may concern.'

Be it known that I, @HARLEY HIPPMAN, la citizen of the United States of America, residing at Kuhns Crossing, in the State of Colorado, havey invented newanduseful improvements in Train-Stopping Apparatus, of which the following is a specification.

This invention relates toimprovements in automatic train stopping apparatus and has particular application to a track obstacle.

In carrying` out the presentinvention, 1t

is `my purpose to provide .a track obstacle which may be associated with a road signal yand which will be capable ,of operation to active position when the road signal blade .moves to danger position and which maybe rendered inactive when thevroad signalblade designates clear. ,f l

It is also my purpose to improve and simplify the general construction of track obstacles and to provide an obstaclewhich may be installed and .maintained .at comparatively small cost, which will operate eiliciently and effectively for `its intended purpose andwherein thecomponentvparts will be so arrangediand correlated as to reduce the possibility of derangement to a minimum.

l/Vith the above and othery objects in View, the invention consists in ythe construction, combination and arrangement of parts hereinafter set forthin 1 and falling within the scope of the claims. j

In the laccompanying drawings: Figure 1 is a view in side elevation of my improved track obstacle. F ig. 2 isa vertical sectional viewy through the sama/parts being shown in elevation. F ig. 3 is a crosssectional View y on the line 5 5 .ofFig 1. Fig. 4 is a like view on the line 6-6 of Fig. l. Fig. 5 is a diagrammatic view showing thecircuit connections of the track obstacle andthe circuit l` connections for the motor carried I on the ,v

In accordance with my present invention, t

vtrack obstacles are disposedV along the trackway and spaced apartappropriate distances and,if desired, these track obstacles may be arranged adjacent to the respective road signals and .controlled therefrom. j Each track vobstacle comprises a base 15 constructed of y anyy suitable material land appropriately fastened tothe road bed and disposed adja-r centy to one side of the trackway. `Secured `to theupper surface of the base 15 centrally iv thereof and upstanding therefromy is a pivot o Specification of Letters Patent. i Appia-ation fue@ Maya 1915.

'ductors 29l are connected with the Serial No. 25,757.

rod 16 and rotatablymounted upon the pivot rod 16 is a vertical post o-r standard 17'capable of rotarymovement in one direction fr or the other. I Suitably secured to the upper surface of the base 15 at diametrically oppo-y site sides of the post 17 are pairs of contacts 18,19 yand fastened to the kpost 17 and radiating therefrom is an arm 20 having the. outer end thereoffequippedwith a pair j of contacts 21 spaced apart and adapted `to `engage the contactsjof either pair 18,r 19, acf nien.

cording lto the direction of rotationvoffthe post 17. Secured to the post 17 adjacent'to the upper` end thereof are outwardly projecting arms 22 spaced apart verticallyand disposed in parallelism with each other. In

having one end connected to the post 17 kand ythe opposite end slidably receiving yone end portion of the section 24. Mounted within the section 2,4 is acoiled expansion spring lating disk 28.V The rollers 27 arekiformed f of material capable of conducting an elecythe present instance, each arm 22 comprises A telescopic sections 23'and 24,-the section 23k tric current and connected to the respective rollers through the medium of rings and ybrushes are the terminals of conductors 29,

while the remaining terminals of theconl respective contacts 2l on the arm 20.

The yswitch 30fmay controlof a `road signal.

Vconjunction With my improved track.V .obstacle may be of any suitable .or preferred construction andv'embodies an electric motor 3 and a pair of contact strips 10v suitably se;-V

cured to the locomotive connected With the yrespective terminals of the motor 3 bymeans of lconductors 11. Located in the conductors 11 is a double'pole single throw switch 12v whereby the connections between the contact strips and the-motor may be made and broken.A Themotor ySis connected through suitable mechanism With a controlling ele- -ment of the rpropelling power ofthe motor 'car and with the brake valve iso that When -tlie motor is energized Athe propelling power 4of the ycar will be' cut oil and the brakes In practice, Vassii-ining the switch r`30150 'be if mainstay' tomroiiai and ioeatea in a road to hold the 'rollers 27 into engagement with Y 'station and assuming 'that' the station agent vwis-hes to bring al train, moving in one direc-` 'tion,to -a standstill, the blades of the switch 30 are Ithrown yinto engagement With the Ajya'vvsfofthe switch connected with, the particu'lar set of contacts 18 or 19,1therebyef- *footing 'a connection iot-ittveiai theY storage battery 33 and the particular set l.of lcontacts. Ast-he train runs 'by a track instrunient', the contact strips 10 engage and ride overtherollers 27 respectivelyand when the rollers 27 are initial-ly engaged by the Contact `strips 10, 'the ypost `17 is revolved under the actfion ofthe moving car and the contacts L21 on lthe arm 20 engage the'particular pair of ycontacts 18 or V19,` depending upon the direction of 'travel ofthe tra in,thereby connecting the motor 3 on the train With the 'battery 33 so that then/motor will be energized to operate 'the cut off device and 'brake valve. Thus, the train Wil'l'be automatically stopped. 'By means ofthe telescopic arms '22 and the springs 25 therein the: sections of the yarms are .permitted to move relatively lto 'one another When'the rollers are engaged bythe contact strips l10 and the springs act the vstrips 10 under pressure, ythereby 'insur-V ing good electrical contact ybetvveei'i the parts. ySprings 34 are connected with'Y the post 17 at diametrically opposite points and act to maintain the post in normal position, that is, in a position to :hold the arm *20jv v'normally 'between `the pairs of contactsv 19 and restore Athe same to such positionl succeeding the release of the Contact rollerspby the 'strips' 10. ltpvvill, ofcourse, be understood that the strips '10 carried by the loco` motive will be ,of such 'length 'as to insure `the closing of the 'circuit of the motor 3 for Y a suliicient'l'eiigth 'of time to operate the car Y carried `stopping mechanism.

While I A'have herein shown Y'described thepreferred formsof myinventonby way of illustration, I Wish 'itV .to Ybe understood that I do `not limit 'or conline'myseli' to the preciseA details oi construction herein described ,anddelineatech as modification and variation may be madewvithin the scope oi oi' the invention.
